Secure LDAP over SSL.
LDI
Library Drive Interface.
LED
Light-emitting diode.
library certification
In cryptography, a certificate that is provided by the library.
library-managed encryption
Tape encryption that is controlled by the tape library.
Linear Tape-Open (LTO)
A type of tape storage technology that is developed by the IBM Corporation, Hewlett-Packard, and Quantum. LTO technology is an "open format" technology, which
means that its users have multiple sources of product and media. The "open" nature of LTO technology enables compatibility between different vendors' offerings
by ensuring that vendors comply with verification standards. The LTO technology is implemented in two formats: the Accelis format focuses on fast access; the
Ultrium format focuses on high capacity. The Ultrium format is the preferred format when capacity (rather than fast access) is the key storage consideration. An
Ultrium cartridge has a compressed data capacity of up to 15 TB (2.5:1 compression) and a native data capacity of up to 6 TB.
liquid crystal display (LCD)
A low-power display technology that is used in computers and other I/O devices.
loadable
The ability to be loaded.
LME
Library Managed Encryption.
LTO cartridge memory (LTO-CM)
Within each LTO Ultrium data cartridge, an embedded electronics and interface module that can store and retrieve a cartridge's historical usage and other
information.
LUN
Logical Unit Number.
LVD
SCSI Bus Low Voltage Differential
M
MAC address
The Media Access Control address of a computer networking device.
magnetic tape
A tape with a magnetic surface layer on which data can be stored by magnetic recording.
MAP
Maintenance analysis procedure.
mask
A pattern of characters that controls the retention or elimination of portions of another pattern of characters. To use a pattern of characters to control the retention
or elimination of portions of another pattern of characters.
master file
A file that is used as an authority in a job and that is relatively permanent, even though its contents might change. Synonymous with main file.
Maximum Transmission Unit (MTU)
The size of the largest packet that a network protocol can transmit.
MB
Megabyte (expressed as data rate in MB/s or MB/second).
media capacity
The amount of data that can be contained on a storage medium, expressed in bytes of data.
media-type identifier
Pertaining to the bar code on the bar code label of the IBM Ultrium Tape Cartridge, a 2-character code, L1, that represents information about the cartridge. L
identifies the cartridge as one that can be read by devices that incorporate LTO technology; 1 indicates that it is the first generation of its type.
mega
One million of.
meter
In the Metric System, the basic unit of length; equal to approximately 39.37 inches.
MIB
Management Information Base. Information repository that is used by SNMP.
micro
One millionth of.
microcode
(1) One or more micro instructions. (2) A code, representing the instructions of an instruction set, which is implemented in a part of storage that is not program-
addressable. (3) To design, write, and test one or more micro instructions. (4) See also microprogram.
microdiagnostic routine
A program that runs under the control of a supervisor, usually to identify field replaceable units.
microdiagnostic utility
A program that is run by the customer engineer to test the machine.
microinstruction
A basic or elementary machine instruction.
microprogram
A group of microinstructions that when run performs a planned function.
The term microprogram represents a dynamic arrangement or selection of one or more groups of microinstructions for execution to perform a particular function.
The term microcode represents microinstructions that are used in a product as an alternative to hard-wired circuitry to implement certain functions of a processor
or other system component.
MIM
Media information message.
mm
Millimeter.
